As with portfolios and investing styles. I think if one adjusts to markets of today. Sometimes our views on investing matters do change, and this sometimes makes what we once might have said, hypocritical. Self Consistency and your ability to adapt to changing market conditions with your own portfolio does play a role -IMO.
If your not following a set of disciplined specific variables. I personally believe you have to make decisions on stocks on case by case basis with relation your style and adapting in newer techniques of today's changing market conditions .Personally I take into account. My success and mistakes, and that determines how outside my own style I will venture. Of coarse my personal consistency over the long haul plays a big role. For myself and other individual investors it's easy to gauge. Just check you schedule D's over the long haul.
